실험 절차

2-(6-acetylaminoindan-1-yl)acetic acid, 3-(6-acetylaminoindan-1-yl)propanoic acid and 4-(6-acetylaminoindan-1-yl)butanoic acid were prepared from 6-nitro-1-indanecarboxylic acid by classical chain elongations by using KCN or diethyl malonate. The methodology is described for an analogous indane serie by R. Gruber et al. Tetrahedron 1974, 30, 3605-10. Alane was used for the reduction of the intermediate carboxylic acids.
